re: Plagiarism

in this bulgarian e-commerce site even remove our logos and watermarks and insert theirs! I sent messages via e-mail and on the online form without an answer.
This is my cake

and this is what they sell saying that a Bulgarian master did it http://sladka-bulgaria.bg/en/dekoratorska-cake-masha-and-the-bear?sort=p.model&order=DESC

and this site put its own logo where it was mine

they do not have an email and if I try to send an online form I have to type a captha in persian that i can not even translate with google translate :(
What can we do?
